Where to go next?

Hello,
It realkly depends on what you've actually done to get it this colour you have now? When did you last lighten it? And do you have a picture? It would help us more to help you 🙂

First I used colourB4 and it turned my hair from dark brown to light brown.
Then I waited a couple of days and bleached it with Born Blonde (Clairol) which turned it yellow at the ends and roots and the rest dark orange/ red.
And then after another couple of days put a medium ash blonde on my hair, which made my roots and ends light blonde and the rest pale orange/ ginger.

I've left it for a week and a half (doing conditioning treatments etc)

Edit: I've taken some pictures, excuse the cruddy quality and the blue (I'm touching it up tomorrow)

Thank you

ok, so don't bleach, you need to wait a couple more weeks/a month otherwise the closest you've got to blonde will be chopped off soon.

try toning before you bleach, if you're a pale orange then look for a blue or a blue violet shampoo, maybe try 'touch of silver' from boots, that's one I've used but others use different ones, this can try and tone out some of the orange. You may think the condition is nice now but I promise you, after a couple of weeks it won't. My hair went stretchy and always felt wet after I processed too many times then I had to cut my just past shoulder length hair off to my chin.

Thanks for the advice, I'll wait 🙂

I actually bought that toner but haven't tried it yet, will do tonight!

By the looks of things, you may get a better result by using another one or two rounds of colour remover first. I can't remember how long after bleach you should wait (because it can be drying) but I'd definitely give it a go before touching bleach again.

After using a colour remover, it's best to wait four weeks before using bleach (don't forget box dyes contain peroxide!)  to prevent your hair from reoxidising and going back dark again. And it's also best to wait a month between using bleach to try and prevent as much damage as possible.

I'd get hold of a decent reconstructor (like Joico K-pak) and baby your hair for a couple of months before using any more bleach as you've double processed your hair already.

I would use another color remover or two. One box would probably be enough for a couple applications since it's just your midlengths pretty much that need it. With dark dyes, especially if you've been dying repeatedly over time, can take 2-3 color remover applications to remove it all, sometimes even 4 in extreme cases like using permanent black/dark brown for 15 years. I really think you would benefit from it because it still seems like there's some color still left in your hair. I would wait though at least a week to get some moisture back in your hair. Do overnight coconut oil and olive oil treatments, do not use any conditioners or treatments/products with silicones in them because they'll block the good ingredients in treatments from absorbing. I would do a couple vinegar rinses to help close your cuticle, which you can do after rinsing out your conditioner/treatment. I wouldn't use any heat on your hair at all, try to stretch your washes, and use a sulfate free shampoo. I would do a reconstructing treatment too like Joico Kpak DPR, Aphogee 2 in 1, or mix some eggs with oil and let it set on shampooed wet/damp hair for a few minutes. You'll want to do these things to restore and balance the protein/moisture in your hair before you do anything else, even a color remover, as the added dryness can push compromised hair over the edge and make it brittle and start breaking.

Definitely another color remover though. then in at least a month, you can check the true condition of your hair to see if it's in good enough shape to lighten again. Just clarify, don't condition, and let it air dry.

In the meantime - treatments and oils, and you can tone it. On the orange areas you can use a blue semi heavily diluted in conditioner, and use violet on the rest to tone. Just really baby the heck out of your hair for the next few months. You've double processed it and done 8 weeks worth of lightening in a matter of 4 days or so, and those box blondes always have 30 or 40 vol in them. So your hair has been through a lot with just that, added to whatever processes you've done to it previously. So avoid silicones - they will mask the damage, making you think your hair is much healthier than it really is, no heat, treatments, oils, vinegar rinses, stretch your washes, or have a look into CO washing. You may notice some breakage over the next month, it can take that long, sometimes even longer for the full extent of the damage done to really show

I've got a similar problem I guess.. When I was totally ignorant of hair-anything topics, I went to a hairdresser that took me from dark brown to coppery medium brown, I don't recall them using bleach and then layering the colour I wanted over it, I think they used high peroxide + the colour I wanted, then in few months time, I went lighter from this medium coppery brown to more of a golden brown, at hairdresser's as well (different one) and I'm not sure if she just bleached my hair or if she used a colour+peroxide, but I remember she first kept me with (I presume) bleach on for about 20-30 minutes, then she saw it didn't lift, so then she applied something crazy (I'm afraid it was 40vol :O) and the colour lifted within like 5 minutes I'm not even kidding... so then I went blonde, I'm like a dark yellow blonde now (btw all these hair tortures happened during a course of a year, so don't panic 😀 could You imagine if I did all that in one week?eeeeekkk) , but some of the hair in midlengths still has this coppery-gingery-orangey tint to it... I've bleached them myself and it's better than it used to be but there's still some orange/brown in there... and I want to achieve clear blonde, is there a point messing around with colour removers/strippers? I don't know if this gingery bits are permanent hair dye, or my hair... but I presume it's the dye as my roots lifted to clear blonde without gingery bits and the only bits that are orange are the ones that have been dyed in the past. Sorry for such a long post 🙁 thanks!

I think colour removers are always worth a shot. They don't damage your hair and will make bleaching much easier.
I have gone from permanent black with several years of build up, to blonde on two separate occasions.
The first time I just bleached it out, and had a lot of unevenness, and bright orange to deal with. All my hair needed bleaching at least three times, and it was only a dark golden blonde at the end. This was many years ago, before the invention of colour removers.
The last time I used a colour remover twice, when I bleached it was much more even and it didn't go bright orange. I actually did several bleach baths over time rather than full on bleaching, so I can't compare directly, but the result was paler and more even, and much, much less damaging to my hair.
